Prevalence of thoracic vertebral fractures in hospitalized elderly patients with heart failure.

OBJECTIVE

Heart failure (HF) has been associated with increased risk of fragility fractures. Indeed, most literature data on fractures were based on an historical and clinical approach focused on the identification of peripheral fractures, whereas the risk of vertebral fractures in this clinical setting is still unclear.

DESIGN

Cross-sectional study.

AIM

To evaluate the prevalence and determinants of radiological thoracic vertebral fractures in patients with HF.

METHODS

The study includes 1031 elderly hospitalized patients (491 females and 540 males; median age, 75 years; range, 65-90; 430 patients with HF) who were evaluated for the presence of thoracic vertebral fractures by quantitative morphometric analysis, using chest X-ray routinely performed in the diagnostic work-up of HF.

RESULTS

Vertebral fractures were found in 166 patients (16.1%), the prevalence being significantly higher in patients with HF as compared with those without HF, both in females (30.9 vs 15.8%; P<0.001) and in males (16.4 vs 7.4%; P=0.001). The association between HF and vertebral fractures remained statistically significant (odds ratio, 2.14; 95% CI, 1.25-3.66; P=0.01) even after adjustment for age, sex, loop diuretic therapy, anticoagulant therapy, proton pump therapy, coexistent chronic obstructive pulmonary disease, diabetes mellitus, renal insufficiency, and chronic liver diseases. In patients with HF, vertebral fractures were positively correlated with female sex, duration of HF, ischemic heart disease, cigarette smoking, and treatment with anti-osteoporotic drugs, and inversely correlated with left ventricular ejection fraction.

CONCLUSIONS

Hospitalized patients suffering from HF are at higher risk of vertebral fractures than patients without HF in the same clinical context.
